' Perth Amboy, in the county of Middlesexb v theirapexes are-farthestremoved from'the l Be it known that I, PETER F. 'HUGHES,

a citizen'ofthe UnitedStates, residing at State of 'New Jersey, fhaveinvented a new and useful Improvement -in Sugar-Cane Mills, of whichthe'following isa f ullj clear,

and exact description, reference being'had .to the accompanyingdrawings, forminga part of this specification;

My invention relates to a sugar ca-neinill,

or more specifically Stated, to a sugar cane to so produce a sugar canemill` roller that the juices expressed from cane' passingbetween Said.roller and a companion roller will be discharged. readily and qui cklyfrom mill roller, Thev invention has for its object vthe point atwhichthe pressure is exerted `upon the cane, and from th'e roller surface infront of such point, instead lof being. car- I ried between the pressurerollers, or becoming-banked in front 'of Such rollers.

' partly in Across Section.v

pressure roller' 3. 4'5" Figure Iis an end elevation of a sugar canemill having rollers therein constructed in accordancewith 4the presentinvention,`

the ends of two of tlie rollers being shown Fig. II is atop or plan viewof portions of the rollers shown in Fig.- I.

Fig. III is air` enlarged view of aA frag' l ment of, one o fthe'lower-rollers and afragin ent vof the top roller, the rollers being`shown partly in 'elevation' and'partly in longitudinal section.

. Fig. IV-'s a view similar to Fig. III, illustrating' a. modification.v

In Fig. I of theaccompanying-drawings' I have shown tlireeiiillers in'triangular ar 'rangement as they appear when mounted Vin a cane millhousing. This arrangement is that preferred vin utilizing Imy improvedrollers, and" I will vdesignate `tliese\rollers. as

the feed vroller 1, delivery roller 2, and top. The rollers 1 -and2 aresimilar, lioivever,and either' of these may be f tlie feed roller andtlidother the delivery roller. f Each 0f the after 4another throughotthe. length of the nallyl of .the-roller and the Sides of the-2idjoining sections beingfin juxtaposition to" thereby fori/ ning4circular valeach other,

rollers land 2 is formed with a succession of crown .sections'Apresentone v leys (ir-gutters between lthe apex 'of-.one

-crwn section and the apex of the n extad 'joining crown section. Thecrown sections v specification of Letters Patent. 'A .fatellted May Q2',1917 Appiiation tied september 15,1915. seriaiiiaaoj'u.' I f i i beingarched longitudinally ofthefroller,.

axis of the roller and the sides of the crown sections are nearest'theaxis of the roller.

The top pressure roller 3 is formed with 'I 'crown sections B Similar tothe crown secitions A upon the rollers 1 and 2, and said crown SectionsB are so located upon the roller 3' thatthey opposethe'yalleys orgutters betweenthecrown sections A'while the I concave surfaces, theconcave Surfaces of one roller being directly oppsed-\'to-the. A

convex surfaces `of the opposite roller so thatfthe 'rollers 11 and 3andthe rollers 2 -crown sections 'A oppose the valleys oftlief and 3 mayapproach each 'other .in the .same manneras they would if theyl were oftlie'same diameter from end to end.'

When sugar caneis passed between the top pressure roller 3 and the feedroller the juices expressed fromthe cane are'permitted to flow not onlycircumferentially of the feed roller, 'butalso'longitudinally of'saidroller along the crown Sections A toward the bases of the guttersbetween the adjoinin crown sections. The juices,therefore,`

'co lectin the' gutters'between thecrown sections, forming rivulets inwhich the juices flow much morequickly than they would' in- 4flowingin'thin films having -a course of 'pas-d 'sage circumferentially.of the roller only The ijnore rapid escapef'of the'juices is due to'thefspeedy collection of. the juices in in# 4creased volume in the'gutters between ythe crown Sections A.

.As the bagasse, passes between the top` pressiirerollei` 3 andthe-delivery rollerthe juices remaining 'in'theca'ne or bagasse c'ol- V100 tions .of Said delivery rollerand esapefrom- 'said rollerin the samemanner asvv they es- `cape from thefeed roller. 4-

. All ofthe rollers arelpreferably 'grooved lect in the gutters betweenthe crownsecor. ribbed-cireuinfereiitiallyg'as Shown in the drawings,butifdesired,rooving .of the rollers may .be dispensed .wit

The feed delivery rollers may be pro-- i videdwith annular grooves C.extending town'rdlhelaxis of the roller from the bases of the guttersbetween the crown sections A, as shown in Figs. I to HI inclusive; hrt-owhich the juices flow for more 'speedy esczipe. Such grooves may,however, be dispensed with and the feed and delivery rollers may beprovided with crown sections A', the bases vof which join each other, asseen in Fig. IV.

Itwill be apparent that in the use of a cane mill .containing rollers'constructed in aeoordance with this invention the grooves upon thecrown sections, .where such grooves are present, may become filled withcane and bagasse and therefore the cane juices may flow readily acrossthe tops of the ridges i between the grooves in their travellongitudinally of the rollers down the sides of the crown sections whenescaping from the rollers.-
